HAIB-PERMANENT-WAVING APPARATUS Application filed July 26,

This invention relates to apparatus for use in connection with hair permanent waving and more particularly to apparatus for holding the hair in a fixed position during the permanent waving. treatment.

An object of the invention isto provide new, simple, eflicient and inexpensive apparatus for use in connection with hair permanent waving.

Various devices have been in use heretofore for holding hair in the desired position during the permanent waving treatment but all of said devices have been found to be unsatisfactory. In some of the apparatus used the protector which rests closely against the scalp .of the patient has been of such thickness as to prevent the hair close to the scalp from being waved and moreover the material of which the protector has been composed was such as to transmit some heat to the scalp thereby causing discomfort. Moreover, in some of the arrangements heretofore used the spool on which the hair was wound was so secured to the protector during the application of heat that it became necessary to move the spool such a considerable distance longitudinally upon the completion of the treatment for unwinding the hair that further discomfort was inflicted uponthe patient. J r According to the present'invention the difficulties found in the devices commonly used have been overcome by providing a protector of such material as to p'ermit the same to be made relatively thin and at the same time to prevent the transmission of heat to the scalp of the patient- The material of which the protector is principally composed is such as to form a good heat insulating material and the protector is so constructed as to permit the hair close to the scalp to become waved as well as that remote therefrom. In order that the hair may be removed after the treatment without causing strain thereupon the present invention provides a spool used in conjunction with the protector. provision be ing made that the spool may be disengaged from the protector with a minimum of longitudinal movement.

' Referring now to the drawings, 10 indicates a protector for use in connection with hair permanent waving upon which and to which is secured in a manner hereinafter to be explained a spool 11 upon which the hair is wound. The protector 10 is composed of -a pair of relatively thin strips 12 and 13 of 85 suitable heat insulating material'which are joined together at one end by means of a cross bar 14 which is rigidly secured to the strip 12 and pivotally secured to the strip 13 thereby permitting the strips to be moved pivotallv with respect to each other. The heat insulating material is preferably Bakelite but it is to be understood that any other material having suitable properties may be used efficiently. The strips 1:2 and 13 are provided at one end with slots 15 and 18 respectively.

In the slot 15 of strip 12 is pivotally mounted a bar 16 to the end of which is acam-like latch member 17. The bar 16 is adapted to pass through the slot 18 in the end of strip 13 100 and to .be locked in position bymeans of the latch member 17 as shown more clearly in Fig. 4. In order that the protector when resting upon the head of the patient may cause no irritation due to the hardness of the surface thereof a thin strip of felt 19 is affixed to the bottom of each of the strips 12 and 13. 1 Since the hair to be treated must be wound tightly it becomes necessary to provide means for preventing such strain thereupon as would cause discomfort to the patient. For this purpose the inner edge of each of the strips 12 and 13 'is provided with a strip of resilient material 20, such as rubber or other suitable prepartions. It would become evident from this that by this arrangement the hair held between the res'pective strips I of rubber or other suitable resilient material 20 will be so held as to prevent the pull exerted upon the hair from beingtransmitted to the scalp of the patient.

In hair permanent waving the hair must be wound around some substantially cylindrical I object to'form the desired waves. In the prestending inwardly from the side ofstandard entinvention use is made of a spool'21 the body of which is of conventional design and structure and has affixed thereto a catch 22 which tends to hold the hair firmly against the body of the spindle when the same is wrapped therearound. Inasmuch as the hair wrapped around the spindle 21 must not be permitted to slip therefrom during the heat treatment, means is provided for holding the spindle against the pad 10 free from rotation or movement other than longitudinal. For this purpose a metallic standard 23 is affixed to the strip 12, such standard having a vertical portion 24 extending in such manner that when the two strips 12 and .13 are in locked position the standard 23 is in substantially the center of the pad. The standard 23 is insulated from strip 12 by means of a layer 40 of asbestos, and a similar layer 41 of asbestos insulates plate 23 secured to strip 13 from such strip. The portion 24 is provided with a hole 25 in the a proximate center thereof, such hole lying su stantially over the mid-point of the joined strips 12 and 13. Ex-

23- is apawl 26 formed from a portion of the standard 23 such portion being punched therefrom. To the other end of the strip 12 is secured a plate 27. A layer 42 of asbestos serves as a heat insulation between plate 27 .and strip 12, while a layer 43 ofasbestos, se

cured to plate 27, serves as insulation between the plate and strip 13. Alfixed to the top of unember 27 is an upstanding substantially U-shaped member 28 for receiving and holding in place one end of a spool 21. Y

The spoo 21 is provided at one end with an enlarged shoulder 30 the end of which is toothe'd'as shown at 31 to form ratchet teeth'for engagement with the projection 26 which acts as a pawl for such teeth. Extendsubstantially U-shaped member 28.

wrapped around the spool 21, which as shown has a varying diameter tapering from the minimum at the center thereof to the maximum near the ends thereof, such tapering arrangement permitting the hair to be wrapped around the spool and upon completion of the wrapping to lie substantially flat as illustrated more clearly in Fig. 1. Due to the catch 22 the hair when wrapped around the spool will not ordinarily slip from the spool butit is necessary that the hair should not unroll during the heat trea'tment. Accordingly as the hair becomes wrapped around the spool close to the pad 10 the 'pin .32 is inserted in the opening 25 and rotation continued. As this rotation continues the ratchet teeth 31 engage successively the pawl 26 and due to the tension on the hair when thespool is rotated as much as possible by means of a wrench or other suitable tool engaging projections 33 on the end of the spindle the pawl 26 in connection with one of the teeth 31 will prevent thespool from rotating and will not permit any movement of the spindle other than longitudinal. In this position the end of the spindle 21 opposite from shoulder 30 rests in and is supported by iftthe er the heat treatment is completed it becomes necessary to move the spool 21 a slight distance longitudinally, such distance being merely suflicient to permit the disengagement of pin 32 from opening 25 after which the hair may be unwound'from the spool.

From the foregoing it will be seen that due to the thinness of the rotector 10 the hair may be waved very closely to the scalp and at the same time the thinness of the protector does not ermit transmisison of heat to the scalp of t e patient due to the fact that the strips forming the protector are of heat insulating material and also that a minimum number of metallic parts are utilized. Moreover the provision of the layers 40, 41, 42 and 43' of asbestos hereinbefore described serve to prevent transmission of heat from standard 23, plate 23" and plate 27, with which the spool contacts, to thestrips l2 and 13 and thence to the scalp of the atient.

The modified embodiment il ustrated in Figs. 7, 8 and 9 consists of a protector 10' composed of parts'similar to those composing -protector 10 with the exception that a different type of standard is utilized in the place of the standard 23 of pad 10 and likewise that the end of the shoulder 80' is somewhat different from the end of shoulder 30. Similar parts are given similar numbers with the addition of a prime to each numeral. In this modification the standard 23' is provided with a pawl 26' similar to pawl 96 but in place of the opening the standard is provided with an annular flange or rim 35 which extends substantially entirely around the standard. Furthermore, the spindle 21 is provided with ratchet teeth 31' but is not provided with a pin similar to pin 32.

In the operation of the modification just described the hair is aflixed between the edges of the strips of the protector as before and the hair wrapped around the spindle 21 in the same manner as previously described. Upon the completion of the winding the spindle 21 will be held against rotation in the same manner as previously described and will be held against any movement other than'longitudinal by reason of the annular flange 35 which serves the same purpose as the pin 32 and opening 25..

From the foregoing it will be seen that the present invention provides an improved apparatus for the purpose set forth. By providing a pawl member punched from and forming an integral part of the standard, a

' more durable and simpler structure is obtained. The invention is not to be limited to the illustrated embodiments but only by the scope of the appended claims.
